Abstract
The utility model provides a porcelain core and silicon rubber umbrella cover combined insulator, which is composed of a porcelain rod and silicon rubber umbrella covers arranged on the porcelain rod. The utility model is characterized in that the inner margins and the outer margins of the two silicon rubber umbrella covers are respectively provided with concave stands which are mutually buckled up and down, and glass fiber insulation layers for adjustment are arranged between an inner circle wall of the mutually buckled silicon rubber umbrella covers and a porcelain core. The utility model not only solves the difficult problem of volume production, but also enables the length of products to be optionally adjusted according to need. The glass fiber layers not only covers the shortage of the low precision of the porcelain core rod, but also increases the intensity of the porcelain core rod, therefore, the utility model has the advantages of light weight, high rigidity, good toughness, high combination mechanical performance and strong dirt resistant performance.
Description
The utility model relates to a kind of High-Voltage Insulation element, relates in particular to the combined insulation element that a kind of high voltage power transmission and transformation are used.
The high-voltage strut insulator that is used for the high voltage power transmission and transformation at present mostly is full porcelain or porcelain, silica gel composite insulator greatly, the former Heavy Weight, and useful life is short, and antifouling property is poor; Latter's mechanical strength is limited.Though this is had a lot of researchs both at home and abroad, its structure is still not ideal.As a kind of electric railway 25KV built-up pillar insulator that Britain Raychem company proposes, it is the silicon rubber umbrella cover of suit thermal contraction after being coated with fluid sealant on the porcelain rod, and this structure is the price height not only, makes difficulty, and is difficult to be applied in the actual production.Chinese patent discloses a kind of " high voltage combined insulation post insulator " for this reason, and its application number is 92206160.2, and its umbrella cover is made up of a plurality of full skirts, and each full skirt is separated from each other, and segmented sheathing is bonded on the porcelain knob outer surface.This silica gel umbrella cover is bonded to the still unresolved silica gel sheath of insulator on the porcelain spare and this critical problem that cooperatively interacts between the porcelain knob, thereby be difficult to form in enormous quantities aborning.Therefore, must improve existing product, to satisfy actual needs.
The purpose of this utility model is to overcome the deficiency of prior art, provide a kind of silica gel sheath and porcelain spare mutual cooperate tight, firmly and easily produce mechanical strength height, the composite insulator that antifouling property is strong.
The utility model is realized by following technical proposal: it is by porcelain knob, be located at the silicon rubber umbrella cover on the porcelain knob, it is characterized in that the inner edge of two silicon rubber umbrella covers and outer rim are respectively equipped with up and down the concave station of snapping mutually, and between the inner round wall of the silicon rubber umbrella cover of snapping mutually and porcelain core, be provided with the fiberglass insulation of regulating usefulness.The inner edge concave station of described silicon rubber umbrella cover is located at the bottom (or top) of this inner edge, so that match with the inward flange of another silicon rubber umbrella cover.The outer rim concave station of described silicon rubber umbrella cover is located at the top (or bottom) of this outer rim, so that match with the outward flange of another silicon rubber umbrella cover.Described inner round wall and the adjusting between the porcelain core outer wall of being located at the silicon rubber umbrella cover forms by the alkali-free glass fiber cloth that scribbles epoxy resin on it is overlapping with fiberglass insulation, be used to adjust the fit dimension between porcelain core and the umbrella cover, thereby remedy the porcelain core rod deficiency of inaccessible degree of precision in process of production.
The utility model compared with prior art has following advantage and good effect: because two silicon rubber umbrella covers adopt the concave station on the inside and outside edge and the structure of outer, the mutual snapping of inward flange with matching, simplified manufacturing of product, not only solved and produced difficult problem in enormous quantities, and the length of product can be adjusted arbitrarily as required; In addition owing to be provided with the fiberglass insulation of adjusting the fit dimension between them between porcelain core and the umbrella cover, not only remedy the porcelain core rod deficiency of inaccessible degree of precision in process of production, and the porcelain core rod that production is fine and close, intensity is high is become a reality, therefore, make the insulator of the utility model have lighter weight, comprehensive mechanical performance and stronger anti-filthy performances such as higher rigidity, toughness.In addition this structure of the present utility model also can be used on other insulator product such as wall bushing.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is another structure chart of silicon rubber umbrella cover of the utility model.
Below in conjunction with accompanying drawing the utility model is described further, is not limited to this but hold within the utility model.
Among the figure, 1 is the porcelain core rod, it can be solid pole, also can be hollow pole, the 2nd, be wrapped in adjusting insulating barrier on the porcelain core rod 1 with the alkali-free glass fiber cloth that scribbles epoxy resin on it, 3 is termination silicon rubber umbrella cover, the its inner rim bottom is provided with the concave station 4 that the inward flange with another silicon rubber umbrella cover 6 is interlockingly connected, 6 is stage casing silicon rubber umbrella cover, and its outer rim top is provided with the concave station 5 that the outward flange with umbrella cover 3 is interlockingly connected, and the inner edge bottom is provided with the concave station 7 that is interlockingly connected with another umbrella cover inward flange.8 is another silicon rubber umbrella cover, and its inner rim top is provided with concave station 9, and the outer rim bottom is provided with concave station 10, is interlockingly connected with the inward flange of its top umbrella cover and the outward flange of bottom umbrella cover respectively.The utility model is mixed metalwork at solid porcelain rod upper and lower end as required can become post insulator; Mix conducting rod in hollow porcelain rod, mix end cap at two ends, outside middle-end is mixed flange etc. promptly becomes the wall bushing insulator.Under the superhigh pressure grade, also can carry out elements combination in addition.
Claims (3)
1, porcelain core silicon rubber umbrella cover composite insulator, by porcelain knob, be located at the silicon rubber umbrella cover on the porcelain knob, it is characterized in that the inner edge of two silicon rubber umbrella covers and outer rim are respectively equipped with up and down the concave station of snapping mutually, and between the inner round wall of the silicon rubber umbrella cover of snapping mutually and porcelain core, be provided with the fiberglass insulation of regulating usefulness.
